Answer: 0,5, and -4 is the zeros
Step-by-step explanation:
Answer:
3/π Hz
Step-by-step explanation:
Recall that for a cos function in the form
y = A cos Bx
period = 2π / B
frequency = 1/period = B/2π
Given y = -5 cos 6x
A = -5 and B = 6
frequency,
= B / 2π
= 6 / 2π
= 3/π
Slope is the change in y over the change of x. So for the first two points are 4-4 over 6 +2, that turns into 0 over 8 and that's just 0=slope
The second one you just do that same thing and then the answer is -7 over 0 which is an undefined slope
Total cost is $38.16
Multiply 36 by 0.06 (2.16)
Add 2.16 to 36 (38.16)
You did not specify the brother's age, so I make a expression, <em>b</em> as the variable.
(3<em>b</em> + 5) - 11
Now do that with the brother age instead of the variable.
